Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

Pavement performance data, in terms of Falling Weight Deflectometer (FWD) deflection, was collected from 71 test sections available from the LTPP/LTPPM sites and used to develop structural deterioration models for flexible asphalt and sealed unbound…

This report documents the development of interim network level road deterioration (RD) models for the roughness, rutting and cracking of sealed granular pavements.

These RD models can be used at the network level for the strategic analysis of the…

This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.

This report looks at low-cost vehicle classifiers to provide some indication of pavement loading or gross vehicle mass (GVM). WIM equipment is relatively expensive to install and calibrate, and may not be easily installed anywhere in a road network.…

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…

This discussion paper examines the consequences of 'peak oil' for road asset management and identified several key issues as the potential subject of future research to assist asset managers in managing the consequences of 'peak oil'. This paper is…

To assist member authorities in the management of road assets to provide better safety outcomes, this research program has been developed to assess the safety implications of road deterioration, the safety benefits of asset restoration, and the…
